The High School Musical actress, 28, kicked off her bachelorette bash with friends, including close pal Vanessa Hudgens, beginning Thursday night in Miami. "Off to a very exciting weekend :)" Tisdale tweeted before heading to the Sunshine State.

Photos posted on Instagram with the hashtag #turnup4tiz showed Tisdale sporting a white, lacy number as well as a traditional "bachelorette" sash.

Hudgens, who has been friends with the Tis since their days at Disney, gushed about the upcoming soiree earlier this month. "Ashley's bachelorette party will be my first one," Hudgens, 25, told People. "It's so exciting. And, it's so crazy because I just think of us as having fun and being silly and the fact that she is getting married, my mind is kind of exploding."

The women's festivities also included logging some time on a private yacht. The Tis herself posted some fun pics of her crew soaking up the Florida sun on Saturday.

After eight months of dating, Tisdale confirmed her engagement to Christopher French on August 12 of last year. French performs with the alt rock group Annie Automatic and previously dated Kaley Cuoco. He proposed to Tisdale atop the Empire State Building on an evening that must have felt like something out of a movie. "Best night of my life," she tweeted at the time. "We're on top of the world."

The actress and singer later explained that she wasn't looking for love at the time she and French met, but she knew instantly that he was her match. "I was like, 'OK, this is the guy.' And he knew the same thing," she told Ryan Seacrest on his radio show. "It was just this feeling that it doesn't get any better. I can't explain it! It's just natural between us. With other relationships, you're trying too much and trying to make it work and then there's just a moment when you find somebody and you're like, 'Holy s--t! This is so natural.'"

Tisdale has said she plans for her wedding to be "small." But she never said she wouldn't go big for the bachelorette party!
